Metals,
Nonmetals, and
Metalloids
(Vocabulary)
Periodic Table of
Elements
A table in which all the known elements
are arranged by properties and are
represented by one or two letter chemical
symbols.
Metals
Elements which have physical properties
such as good conductivity, shiny luster,
malleability and ductility.
Nonmetals
Elements which have physical properties
such as no conductivity (an insulator),
dull luster, and brittleness (will break).
Metalloids
Elements which can have both properties of
metals and nonmetals.
Also may be called a semi-conductor.
Luster
The way a substance reflects light.
Examples
•Shiny
•Dull
•Metallic
•Waxy
Malleability
How well it can be hammered into thin
sheets.
Examples
•Flattened penny
•Aluminum can
•Tin foil
•Aluminum foil
Brittle
The tendency to break, snap, or crack
without first bending or changing shape
as a result of application of little force.
Conductivity
How well it allows electricity to move
through.
Ductility
Can be stretched into wire.
Magnetism
Attracted to or repelled by a magnet.
Sonorous
An object that produces a sound when
struck by another object.
Conductor
A material that conducts or transmits
heat, electricity, or sound
Insulator
A substance that does not allow the heat
or sound to pass through
Semiconductor
A substance that can conduct electricity
or heat under some conditions but not
others
Density Formula
D = mass/volume
(I
density)
Water Displacement
A method used to calculate the volume of
an irregular shaped object.
Volume Formula
V=LxWxH
